Are characters completely random (like different names, appearances etc) or set characters but random who you can get and start with?

It's hard and has good concepts. Please change the BGM.

Does the game contain hentai scene like the dlsite version?

:) Just played the demo. I really like the atmosphere, but I find difficulty too high, I can't even get to the 2nd floor xD. Add an easier difficulty setting and I'm buying it. Keep up the good work, guys! :)

So I've noticed some enemies follow you and never stop. I initially thought it was some sort of aggro mechanism, but even if you enter a floor and never move, they'll come chasing you from off screen. If you choose escape, they still come for you, making escape pointless. This is pretty annoying. Is this the intended behavior?...
